I went to my fathers for BBQ'd ribs tonight.I had about 20 minutes before they were done.Grabbed the F75 and started hunting by the old clothesline area,next to a lilac hedge.Got a 82-83 ID,dug a 1936 silver Washington quarter,next hit was a 1940 Mercury dime,next hit was a1942 Mercury dime and then I dug a 1946 wheatie.I looked at my watch and I'd been hunting for 12 minutes.I was stunned.There are large overhead powerlines and a transformer about 15 feet away also.All the coins were about 3 inches deep.I have pounded that area with my CZ3D,CZ70 and a Whites M6.I have dug 2 silver Canadian quarters,3 silver Canadian dimes,1 silver Rosie dime and 3 other wheaties in that area.I had a constant crackle of EMI in the headphones but I was still able to tell a coin hit.I walked in the house and handed the coins to my father,he was stunned.He then told me that they were coming out of my inheritance.He is a bad man!! My question to him was"what would you find if you hunted all the yards of the houses on this block?"His is the smallest house and smallest yard.All the houses are at least as old as his.There about 10 more blocks of houses like this,all about the same age.Now that gives me ideas.I tried to post a picture of all 4 coins but I can't figure out how to make it small enough.I'm computer challenged.I felt surgical with the F75 tonight.
